l 2 claims. (c1. 171

This invention relates to means for conveying the heads of animal carcasses during trimming thereof.

One of the objects of the invention is to provide an improved hog head conveyer.

Another object of the invention is to provide an improved means iyor conveying the heads of animal carcasses for trimming.

Another object of the invention is to provide an l() improvedmeansforconveying the heads of animal carcasses through a predetermined path, which path is defined by a series of changing positions suitably adapted for trimming of the heads.

Other objects of the invention will be apparent is from the description and claims which follow.

The device of the present invention comprises a conveying means provided with a series of spaced pins pivotally mounted for movement sidewise of the normal line of travel of the conveying means and guide means for moving the pins through a series of predetermined positions suitably adapted for trimming the heads of carcasses carried thereover.

By way of illustration, but without limiting the scope of the invention, the device will be more specifically described `for use in trimming the heads of hog carcasses.

In accordance with the present invention, the severed heads of hog carcasses are individually mounted on successive pins of the conveying means and are free to revolve through 360 about the pin as an axis. The heads carried on the pins are moved in a predetermined path by the conveying means, sidewise movement being periodically effected to provide a series of successive positions suitably adapted for the several trimming operations.

Reference is had to the drawings in which like characters of reference are used to designate similar elements.

Figure l is a plan view of a conveying means constructed in accordance with the present invention.

Figure 2 is a side elevational View of the device shown in Figure 1.

Figure 3 is an enlarged detail view, partly in section, taken substantiallyon line 3-3 of Figure 1.

Figure 4 is an enlarged side view illustrating one of the head carrying pins'.

Figure 5 is a top plan view of Figure 4.

The device of the present invention comprises endless conveying means I adapted for travel on sprockets 2 and 3 rigidly secured to shafts 4 and 5 journaled in bearings B and 1. Bearings 6 and 1 are rigidly secured to uprights 8 of framework 9 suitably constructed for supporting conveying means I.

Conveying means I is driven by power transmitted from motor III through shaft I I and gear box I2, the gear box I2 being suitably connected with shaft 5.

Conveying means I is provided with a series of spaced pins I3 and may be vertically mounted in framework 9 so that at its discharge end I4 the pins I3 will be revolved in a downward direction to discharge trimmed heads to a slide, or other suitable conveying means, for transfer to a remote point.

Reference is now had to Figures 3, 4 and 5 in which it is seen that conveying means I comprises a series of alternate links I5 and I 6 piv otally connected through suitable openings as by shafts I1, the links I6 being adapted for mesh with teeth I8 of sprockets 2 and 3 and the links I5 being suitably flanged, as at I9 and 20, for rigidly securing pin carrying brackets 2| and 22 as by bolts 23. It will be understood that only links I5 occurring relative to the spacing of pins I3 need be flanged as at I9 and 20.

Shafts I1 are provided at either of their ends with rollers 24 adapted for travel between rails 25 and 26 rigidly secured, as by bolts 21, to opposed uprights 28 and 29 of framework 9. It

will be seen that the shafts I1 through rollers 24 and rails 26 serve to rigidly support the conveying means in a horizontal plane during traveling of the conveying means between sprockets 2 and 3.

Pins I3 are threaded, as at 3|), within opening I3 in its sidewise movement between guide rails 31 and 38. Roller 36 is xed against longitudinal movement on pin I3 by shoulder 39 provided by arm 32 and shoulder 4I! provided by sleeve 4|. Sleeve 4| is rigidly secured on pin I3 as by screw 42. Sleeve 4I is suitably flanged, as at 43, and thus serves as a base for mounting supporting block 44 of wood or other suitable material. Block 44 may be rigidly secured to flange 43 as by screws 45.

Guide rails 31 and 38 are respectively secured, as by arms 46 and 41, to frame uprights 28 and 29. As viewed in Figures 1 and 3, itis seen that Cia guide rails 31 and 38 are suitably formed for con-y trolling the movement of the pins I3 sidewise of the normal path of travel of conveying means I. The pins I3, as illustrated in Figure 3, are adapted for sidewise movement through substantially 75.

In operation, a supply of hog heads on table 48 are individually mounted on the successive pins by an operator. The position of each head, as it is i moved in a forwardly dirction on the conveying means, is automatically corrected by sidewise movement of the pins to the best advantage for the immediate trimming operation. The several trimming operations may be successively performed along the path of travel of the conveying means, after which the trimmed head may be removed for splitting the skull and removing the brain.

I claim:

l. In a device for conveying the heads of animal carcasses during trimming thereof, including an endless conveyer provided with a series of spaced head carrying pins, means pivotally mounting each of the pins for positive sidewise l movement while being moved in a forwardly direction on the conveyer comprising a pivot arm pivotally secured within a bracket rigidly secured to the conveyer, said pivot arm being adapted to rigidly secure one end of a pin, a guide rail mounted to each side of the pin, intermediate the ends of the pin and laterally of the line of carriage of the pin on the conveyer, said guide rails defining in part a path laterally of the path of movement of the conveyer, a roller freely rotatable on the pin and between the guide rails and a carcass head supporting means rigidly afllxed to the pin, said pivot arm and said head supporting means providing bearing shoulders for said roller.

2. In a device for conveying the heads of ani mal carcasses, a pivot carrier, a roller loosely mounted on the carrier, a support above the roller, a head carrying pin extending through the support and roller and mounted in the carrier, the said support and carrier constituting side bearings for said roller, a conveying means' and a guide means associated with said conveyingmeans and said pivot carrier for causing said pin to be shifted laterally in opposite directions successive- 1y.
